Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Facile Approach to Modulating Stereochemistry in Ring‐Opening Metathesis Polymerization of Cyclooctadiene

Journal of Polymer Science, EarlyView.
The stereochemistry of polybutadiene made by ring‐opening metathesis polymerization (ROMP) evolves both during and after polymerization, as secondary metathesis shifts cis‐rich kinetic products toward trans‐rich equilibrium compositions. By tuning catalyst identity, additives, temperature, and reaction time, polybutadienes with 28%–80% trans content ...

Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

Journal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.
